A recently published study in the International Journal of Epidemiology suggests that there could be a correlation between genetics and sex crimes.
Sexual crimes are a large problem in today's society effecting both men and women. One out of every four women will become a victim of sexual assault and one out of every ten men will become a victim.
The 37 year study, from 1973-2009, studying 21,566 men showed a link between the likelihood of a man to commit a sex crime and the past sex crime history in his family. A man whose brother or son has committed a sex crime is five times more likely to commit a similar offense. A man whose father has committed a sex crime is four times more likely. The team also analyzed similar conditions such as child molestation and rape and found similar results. The team analyzed the large quantity of data and determined that 40% of the risk of committing sex crimes is genetic while the other 60% is affected by what kind of environment the man was brought up in.
It is important to note that the researchers have not found the "rape gene". They do suggest, however, that there is a significant correlation between genetics and risk for committing a sex crime.
